Missing audio channels with the ADV7619-ADV7511 eval board

I am feeding a 8-channel HDMI source to the ADV7619-ADV7511 eval board.

The issue is that only the first 2 channels are passed through.

When looking at the register with AVES, on the ADV7619 HDMI register 0x07 bit 6 is set, meaning multichannel audio detected.

I set ADV7511 main register 0x0C to value 0xFC (instead of default value 0xC4) to enable I2S1-3, but it did not have any effect

Can someone help?
